JOHN F. MQMANN, or ROCHESTER, NEW YORK.

SIPHON.

Application filed April 11, 1911.

To all whom it may concern:

Be it known that I, JOHN F. MGMANN, of Rochester, in the countyof'Monroe and State of New York, have invented a new and usefulImprovement in Siphons, which improvement is fully set forth in thefollowing specification and shown in the accompanying drawings.

The present invention relates to siphons and it has for an object toprovide a con struction adapted to cooperate with the ordinarycommercial milk bottle to start a siphonic action, in order that thesiphon may be utilized for separating the cream at the top of the bottlefrom the milk at the lower portion.

To these and other ends the invention consists in certain parts andcombinations of parts all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

In the drawings:

Figure 1 is a side view of the improved siphon as it is being introducedinto the neck of an ordinary or commercial milk bottle;

Fig. 2 is a section on the line a0; Fig. 1; and

Fig. 3 is a bottom view of the siphon showing the fender, that preventsthe direct upward movement of the liquid, removed:

In carrying out the invention, there is employed a siphon 1 preferablymade from sheet metal such as aluminum and having a piston. on itsintake leg so formed that it may be introduced into the neck or themouth of a receptacle such as a commercial milk bottle 2. The pistonpreferably is ar ranged in spaced relation to the intake end of thesiphon and may comprise two aluminum or unyielding disks 3 and 4 spacedfrom each other by a disk 5 of yielding ma terial such as rubber, thedisk 5 preferably projecting beyond the peripheries of the disks 3 and 4so as to provide a yielding free edge which forms an air tight jointwith the internal wall of the receptacle. The piston may be held againstmovement on the siphon in any suitable manner. In this instance, annularbeads 6 are extended outwardly from the metal of the siphon to engagethe outer faces of the disks 3 and 4, thus also holding together thedisks 3, 4 and 5 forming the piston.

To the end of preventing a direct upward movement of the liquid into theintake of Specification of Letters Patent.

Serial No. 620,288.

the siphon so as to confine the action of the siphon to the cream alone,there may be provided a cup shaped fender 7 receiving the intake end ofthe siphon 1 and held in spaced relation thereto from the piston. Withthis purpose in view, the lower disk 4 of the piston has spring arms 8depending therefrom and preferably formed in one piece therewith. Thefree ends of the arms are grooved at 9 to receive the periphery of thefender 7 and finger pieces 10 are provided on the arms 8 below thegrooves 9 for the purpose of facilitating the connection and the releaseof the fender.

In the operation of the invention, the siphon is used as a handle toforce the piston within the neck of the receptacle 2, the resilientperiphery of the piston cooperating with the walls of the receptacle toform a tight joint so that sufficient pressure is secured on the top ofthe liquid to force the cream past the bend of the siphon, thus startingthe siphonic action which will continue as long as the intake end of thesiphon is below the liquid level. If only pure cream is desired, careshould be taken that the intake end of the siphon does not pass belowthe cream, and the fender 7 will act to prevent a direct upward movementof the liquid so that no liquid below the end of the siphon can bedrawn. A siphon constructed in accordance with this inventlon is simplein its operation, inexpensive to manufacture, and not liable to get outof order. Further more it is sanitary, in every respect, as there are noplaces in which dirt or other matter may collect, and the fender isremovable to permit the cleaning thereof and of the s1- phon tube.

That I claim as my invention and desire to secure by Letters Patent, is

1. A siphon comprising an imperforate flexible disk attached to theintake leg, and adapted to coact with the interior of the neck of areceptacle, of which the neck is of less diameter than the body, tocommence a flow of the contents of the receptacle through the siphon,and to pass into the body of the receptacle and expose the contents toatmospheric pressure to allow the flow to continue.

2. A siphon having a piston on its intake leg, and a fender supported bythe piston to prevent the direct upward movement of liquid into theintake of the siphon.

3. A siphon'having a piston on its intake leg, spring arms dependingfrom the piston, and a fender detachably engaged by the arms to preventdirect upward movement prevent direct upivard movelnent of the liquidsinto the intake.

of the liquid into the intake. JOHN MCMANN' 4. A siphon having a disksurrounding its Witnesses:

intake leg, spring arms depending from the A. M. WHITMORE,

disk, and a fender carried by said arms to E. T. WOODEN.
